## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability riley-craig-x402-agent-store-brand-ai-visibility-check-2c2755d3
```

Example prompt: Check how visible Acme Logistics is in AI-generated responses in the logistics software category — I want the visibility score, how many times it's mentioned, and which competitors are showing up instead.

## When to prefer this

Use this endpoint when you need to quantify how often and prominently a specific brand appears in AI-generated answers within a product category — especially for competitive benchmarking or AI SEO auditing. Prefer this over general web SEO tools when the specific concern is AI chatbot visibility rather than traditional search ranking.

## Known failure modes

- Missing required 'brand' or 'category' query params returns an error
- Unknown or misspelled brand names may return a score of 0 with empty mentions
- Payment failure via x402/USDC results in 402 Payment Required before data is returned
- Very niche brands or categories may return low-confidence results with minimal data
